Procedure

A solution of 35 mg (0.054 mmol) of (3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-yl (1S,2R)-1-[4-(3-aminopropoxy)benzyl]-3-[(1,3-benzodioxol-5-ylsulfonyl)(isobutyl)amino]-2-hydroxypropylcarbamate, 22 mg (0.16 mmol) of 2-chloro-5-cyanopyridine, and 38 μL (0.22 mmol) of N,N-diisopropylethylamine in 0.5 mL of anhydrous DMF was heated to 80° C. with stirring. After 6 hours the solution was cooled to RT and concentrated to dryness in vacuo. The residue was purified by flash chromatography (SiO2, 95:5 CH2Cl2/MeOH) to afford 33 mg (80%) of the desired compound as a white foam. 1H NMR (CDCl3): 8.30 (s, 1H), 7.50 (d, 1H), 7.29 (d, 1H), 7.13 (s, 1H), 7.09 (d, 2H), 6.84 (d, 1H), 6.78 (d, 2H), 6.37 (d, 1H), 6.04 (s, 2H), 5.62 (d, 1H), 5.44 (br s, 1H), 4.96 (m, 2H), 4.00 (t, 2H), 3.91 (m, 1H), 3.80 (m, 3H), 3.71-3.49 (m, 5H), 3.18-2.65 (m, 7H), 2.08 (m, 2H), 1.80 (m, 1H), 1.61 (m, 1H), 1.50 (m, 1H), 0.90 (d, 3H), 0.81 (d, 3H). MS(ESI): 752(M+H).
